Cross Sound Cable
The Cross-Sound Cable is a 25-mile (40 km) long bipolar high-voltage direct current (HVDC) submarine power cable between New Haven, Connecticut and Shoreham, on Long Island, in New York, United States. Description The Cross-Sound Cable can transmit a maximum power of 330 MW at a voltage of +/- 150 kV DC. The maximum current for Cross-Sound Cable is 1175 amperes. The Cross-Sound Cable is not simply a pair of underwater HVDC cables; rather it is a bundle of cables that includes the HVDC transmission lines and fiber-optic cables for phone and Internet data transfer. Construction of the Cross-Sound Cable was started in 2002 from the former site of the Shoreham Nuclear Power Plant. The cable was first laid on the floor of Long Island Sound; then a machine known as a jet plow tool used high-pressure water to fluidize the sea bed directly under the cable. The cable then fell into the liquidized trench. Concern over possible environmental impact of the buried underwater cables c ...

Long Island Power Authority
Long Island Power Authority (LIPA, "lie-pah") is a municipal subdivision of the State of New York that owns the electric transmission and electric distribution system serving all of Long Island and a portion of New York City known as the Rockaways. LIPA was originally created under the Long Island Power Act of 1985 to acquire the Long Island Lighting Company (LILCO)'s electric and natural gas infrastructure after the cancellation of the Shoreham Nuclear Power Plant. LIPA acquired LILCO's transmission system in May 1998, while the remainder of LILCO's natural gas-related infrastructure merged with Brooklyn Union Gas to form KeySpan Energy. Before 2014, LIPA's electric and natural gas infrastructure was run under its own name, though KeySpan operated its electric and natural gas infrastructure under a prior management contract with LIPA until 2007. KeySpan merged with National Grid USA in 2007, and National Grid began operating the electric infrastructure portion of LIPA busine ...

Hempstead Harbor
Hempstead Harbor (also known as Hempstead Bay) is a bay hugging the northern coast of Long Island, New York. Located off of the Long Island Sound, it forms the northernmost portion of the political border between the Nassau County towns of Oyster Bay on the east and North Hempstead on the west, as well as the western border of the city of Glen Cove. History Before World War I, shacks were built on the marsh flats in the town-owned Hempstead Bay wetlands. They served as shelters for duck hunters, fishermen and weekend campers. Over time the summer cabins became cottages passed down through generations. Until 1970, folk singer Burl Ives, spent occasional summer weekends in a cottage near the Hempstead Town Dock. Storms and erosion have taken their toll, and North Hempstead officials and conservationists came to consider them an intrusion. Ultimately, the Town stopped granting new leases in 1964. From the early days of colonization until the 20th Century, many farms were located ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electric Power Transmission
Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a ''transmission network''. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery, known as the electrical grid. Efficient long-distance transmission of electric power requires high voltages. This reduces the losses produced by strong currents. Transmission lines use either alternating current (HVAC) or direct current (HVDC). The voltage level is changed with transformers. The voltage is stepped up for transmission, then reduced for local distribution. A wide area synchronous grid, known as an "interconnection" in North America, directly connects generators delivering AC power with the same rela ...
